لا يجوز للمحامي بنفسه أو بوساطة محام آخر أن يقبل الوكالة عن خصم موكله أو أن يبدي له أي معونة، ولو على سبيل الرأي في دعوى سبق له أن قبل الوكالة فيها أو في دعوى ذات علاقة بها ولو بعد انتهاء وكالته.

Article 15 explained in plain English
This Article protects a client's trust in his lawyer by barring the lawyer from switching to the other side of the same dispute.
What is prohibited?
- The lawyer accepting agency for his client's opponent.
- The lawyer giving the opponent any help, even by way of opinion; the prohibition is not limited to pleading but covers merely giving an opinion.
In which case? In the case in which the lawyer previously accepted agency, or in a case related to it.
Does the prohibition end when the agency ends? No. The text is explicit that the prohibition stands even after his agency has ended, and it sets no period after which it ends.
Can it be evaded through another lawyer? No. The prohibition covers what the lawyer does himself or through another lawyer.
The Article is connected to Article 14, which bars a lawyer from accepting a case or giving a consultation against a body he works for or whose relationship ended less than five years ago, and to Article 16, which bars a former judge from accepting agency in a case that was before him. All of them are provisions aimed at preventing conflicts of interest.
If you suspect that your opponent's lawyer previously handled your case or a related one, it would be best to consult a lawyer specializing in the laws regulating the legal profession.
Practical example
A lawyer acted for Ahmed in a claim for money against a company in Dammam, and then his agency ended. Months later the company asked him to advise it on the same case. He may not do so, even by way of opinion, nor have another lawyer do so for him, because the prohibition stands even after his agency has ended.
